Title: Apparatus for sequential multielement analysis by atomic spectroscopy
IPC: G01N21/64
Filed: 1969-08-25
Abstract: 1308610 Spectroscopic apparatus TECHNKON INSTRUMENTS CORP 25 Aug 1970 [25 Aug 1969] 42300/69 Heading G1A [Also in Division H1] In atomic fluorescent or emission spectroscopic apparatus, circuitry is provided for sequentially processing signals due to the emissions from different elements, with appropriate processing characteristics for the respective element signals. The signal for one element might, for example, overload the amplifier, so a different amplification is used for each signal. In the fluorescence analysis of a sample, Fig. 1, sources L 1  - L 4  producing bursts of pulses, are energized in turn to excite different elements in the sample 14. While L 1 , for example, is illuminated, switch SW 1  is closed to alter the feedback resistor used in amplifier 20, which is tuned to the frequency of the pulses of the source, the selection of lamp and switch being under control of device 10 which responds to the positioning in front of detector 16 of a particular filter (in this case F 1 ) of wheel 12. The lamps are operated in sequence with suitable intervals therebetween, so that a sequence of sample signals for different elements is obtained on line 22. The apparatus can also be adapted for atomic emission spectroscopy by thermal excitation for which a D.C. amplifier is required. The apparatus may be modified to provide sequential fluorescence and emission test signals, suitable modulation of the radiation from the atomic emission sample being provided or, as in Fig. 2 (not shown), separate filter wheels and amplifiers being provided for the fluorescence and the emission channels. It is stated that a hollowcathode lamp is suitable for the fluorescence analysis and suitable supply conditions for obtaining pulsed output are described (see Division H1). The apparatus may be provided with means for compensating for light source intensity fluctuations, Fig. 4 (not shown). Photo-diodes are associated with the sources and connected in parallel to a tuned amplifier whose output is fed to a ratioing circuit with the output of the main signal processor to give drift-independent signals. The lamp source intensities may be controlled by feedback or by varying the amplifier gains. In the Fig. 2 system, the sample signals may be used to vary the feedback resistors so as to keep the amplifier outputs constant, the resistor values being indicated digitally.

Title: Electrical transmission networks

Abstract: 1309736 Equalizing networks; active filters; amplifying circuits STANDARD TELEPHONES & CABLES Ltd 23 June 1970 [30 June 1969] 32902/69 Headings H4R H3T and H3U An active all-pass delay network for compensating for group delay distortion (introduced by networks such as frequency selective filters in an electrical transmission system) comprises a differential amplifier with a reactive network (having a delay compensating characteristic) connected to one input and a resistive feedback path connected between the output and the other input of the amplifier. As shown the reactive network ZB is a parallel array of series LC circuits and the gain of the amplifier is determined by the values of resistors R1 to R3 in the feedback path. Mathematical theory derived from a discussion of impedance lattice and bridge T networks shows that if ZB is purely reactive the amplifier has an all-pass characteristic. The circuit may be of integrated circuit construction. It is stated that the inductors may be simulated by RC-active equivalents, e.g. a two-part gyrator circuit using two further differential amplifiers and an inverting amplifier.

Abstract: 1325772 Aerials STANDARD TELEPHONES & CABLES Ltd 19 April 1971 [27 Feb 1970] 9674/70 Heading H4A To obtain an output which is representative of the electromagnetic field at a distant point due to a symmetrical aerial array, the R.F. currents flowing simultaneously in the array elements are sampled, sum and difference functions are obtained by taking the samples in pairs, each pair relating to two elements which are symmetrically disposed about the array centre line, the said functions are individually amplitude weighted in a predetermined way, and the weighted sum functions and the weighted difference functions are added in quadrature. As described, a linear aerial array comprises four dipoles which are disposed in pairs E 1 , E 2  and E 3 , E 4  about an axis of symmetry. Each dipole is monitored for current flow, for example, as described in Specification 1,325,771. The current samples from the symmetrically disposed dipole pairs E 1 , E 4 , and E 2 , E 3 , are feed to respective 180 degree hybrid rings HR1, HR2. Sum outputs from the hybrid rings are connected through respective amplitude weighting networks C 1 , C 2 , to the inputs of a first adder of a combining unit. Difference outputs are similarly connected through networks S 1 , S 2 , to the inputs of a second adder. The outputs of the larly connected through networks S 1 , S 2 , to the two adders are combined by means of another 180 degree hybrid ring, a 90 degree phase changer being connected in the output from the second adder. Formulµ are given for calculating the weighting networks for a required value of #, the angle between the array axis of symmetry or centre line and a line directed towards the distant point. The array may have an even or an odd number of elements. In the latter case, the current sample from the centre element is associated with the sum functions obtained from the other elements.

Abstract: 1344677 Doppler radar GRANLEY PRODUCTS (LONDON) Ltd 2 Oct 1972 [5 Oct 1971] 46310/71 Heading H4D [Also in Division G4] A system for detecting moving objects ineludes a transmitter and means coupling part of the transmitted signal to a receiver; means for applying a test signal to be transmitted by the transmitter and to simulate a received signal and means for detecting whether the test signal is received both by the receiver and at a distant location. In a Doppler radar intruder alarm (which alternatively may use sound waves), operation of main switch 15 sets bi-stables 17, 27 and after a delay 19 triggers an amplitude modulation signal f n  from generator 21, setting of bi-stable 17 produces a signal 18 which inhibits operation of the alarm and lights a warning lamp. Transmitter 11 radiates the signal and receiver antenna 32 receives a leakage signal from which receiver 12 extracts the test signal. A logic signal is passed via latching indicator 25 to gate 26. Gate 26 also receives an input from receiver 24 located on the remote boundary of the protected area (there may be several such receivers), if it receives the test signal. Presence of both inputs indicates correct operation and gate 26 resets bi-stable 27. This triggers monostable 28 and operates inhibit 29 to stop transmission of the test signal. Monostable 28 resets bi-stable 17 which removes the alarm inhibit and indicating lamp thus sensitizing the alarm system.
